Reptiles and Amphibians in the Pacific Northwest

There are comparatively few reptiles and amphibians here; only 38 species, two of them introduced, compared to 9300 species worldwide, and 134 species in Alabama.

The information in this chart is taken from Amphibians & Reptiles of the Pacific Northwest; Nussbaum, Brodie & Storm; University of Idaho Press; 1983. They include illustrated keys to the families, descriptions, photos, habitat, range maps, life history (including food and predators), and references for all of the known reptiles and amphibians in Washington, Oregon, Idaho and British Columbia. I've extracted only those species that show up in the Cascades and westward.

Viperidae - Pit Vipers
